>>31508754It's the result of a legitimate complaint taken too far.
"Because I'm EVIL" is shit-tier villain-writing. Even history's greatest villains weren't born twirling their mustaches. Often, they thought that their actions were justified for one reason or another. And they certainly weren't doing things BECAUSE they were evil--they always had a reason.
So, a villain who had a reason to be villainous--both a past that made them the way that they are and a purpose behind their actions--is, straight-up, better than "for teh evulz."
The issue is that "for power/money/whatever" is actually a legitimate reason to do something, and someone acting for that reason was sculpted that way by the society in which they exist. But it's hard for people to see the impact of a society that they themselves live in, so they look at it and see "evil because evil." Even though it's more realistic than "I want to end the world because daddy never hugged me," it seems less realistic to them because no specific reason is given.
Narrative convention is weird. Sometimes, a more accurate depiction of reality seems less realistic to an audience because it doesn't line up with how things are expected to be presented.
